Glass fibre reinforced composite springs

Based on the individual needs of our customers, we manufacture flat guide springs from a composite of glass-fibre-reinforced epoxy resin. Their special balanced composition ensures optimal dynamic properties.

Key features of high quality flat guide springs:

  1. The flat guide springs have a high elastic energy storage capacity combined with high mechanical strength.
  2. The result: compared to steel leaf springs, they have a much higher elastic effect, higher internal damping and a more balanced elastic behaviour, with a much higher retention capacity of elastic energy than spring steel.
  3. The mechanical properties of the springs can be adapted to different applications by directing the different pre-impregnated layers towards each other.
  4. Result: The overall mechanical strength available is concentrated exactly where it is needed. This ensures that the spring perfectly matches the load.
  5. Flat guide springs provide a balanced ratio of mechanical strength to weight. Further attributes are high fatigue strength with “damage resistance”, corrosion resistance, impact resistance and electrical insulation.
  6. Result: These features enable the construction of high performance, mechanical and dynamic systems. They are used in screening machines, vibrating dispensers and feeders.
